Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-104352-4 is determined by strict alignment with the following critical parameters: 28-position count, 2-row configuration, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, male pin contact type, through-hole mounting, unshrouded design, push-pull fastening, and UL94 V-0 flammability rating. All substitute parts must maintain these core specifications to ensure mechanical fit and functional compatibility within existing PCB layouts and mating connector designs.

Secondary parameters including contact finish, contact material, insulation material, and operating temperature range may vary between substitutes provided the primary specifications remain constant. Termination method variations (solder-only versus press-fit/solder combinations) are acceptable where the solder termination capability is retained. Voltage and current ratings must meet or exceed the original specification of 30VAC and 3A respectively.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain the critical mechanical and electrical specifications required for direct interchangeability with the 1-104352-4. The following selection criteria apply based on product status and regulatory compliance:

Primary Substitutes (Highest Compatibility):

The Amphenol ICC (FCI) parts 77313-802-28LF and 77313-102-28LF represent the most direct functional equivalents, maintaining identical contact geometry (square shape), contact length specifications, and push-pull fastening characteristics. Both parts are active products with RoHS compliance and extended operating temperature ranges (-65°C ~ 130°C) that exceed the original specification. The 77313-802-28LF variant features reduced contact finish thickness (15.0µin) compared to 77313-102-28LF (30.0µin), with both utilizing phosphor bronze contact material and tin post finish.

The Molex 0010897282 (C-Grid 70280 series) provides an active alternative with identical pitch and position specifications. This part features gold mating contact finish and copper alloy material composition, with ROHS3 compliance and unlimited moisture sensitivity rating. Contact dimensions vary slightly (0.240" mating length versus 0.230" in the original), remaining within acceptable tolerance ranges for standard mating applications.

The Preci-Dip 450-10-228-00-006101 maintains core specifications with the exception of contact shape (circular versus square) and contact length parameters. This part offers superior voltage rating (150VDC) and extended operating temperature range (-55°C ~ 125°C). ROHS3 compliance and REACH unaffected status provide regulatory advantages for new designs.

Secondary Substitute (Limited Parameter Alignment):

The Samtec TD-114-T-A-1 meets fundamental position, row, and pitch requirements with active product status and ROHS3 compliance. Specific fastening type, shrouding configuration, and contact shape parameters are not provided in available documentation, requiring verification against application requirements before selection.

Regulatory Compliance Considerations:

The original 1-104352-4 is RoHS non-compliant and REACH affected. All substitute parts listed achieve RoHS compliance (ROHS3 or equivalent), supporting transition to current regulatory requirements. The Preci-Dip part additionally carries REACH unaffected status, eliminating substance of concern restrictions.

Frequently Asked Questions (FAQ)

Q: Can the 77313-802-28LF directly replace the 1-104352-4 in existing designs?

A: Yes. The 77313-802-28LF maintains all critical specifications: 28 positions, 2 rows, 0.100" pitch, male pin contacts, square contact geometry, through-hole mounting, unshrouded design, and push-pull fastening. Contact length variations (0.230" mating length in both parts) and operating temperature extension (-65°C ~ 130°C versus -65°C ~ 105°C) present no compatibility issues. The part is active and RoHS compliant.

Q: What is the significance of contact finish differences between substitute parts?

A: Contact finish (tin-lead, gold, or tin) affects electrical conductivity, corrosion resistance, and solderability. The original 1-104352-4 specifies tin-lead finish at 100.0µin thickness. Substitute parts employ gold or tin finishes at varying thicknesses (15.0µin to 200.0µin). All finishes support standard solder termination and push-pull mating cycles. Selection should align with existing PCB pad finishes and environmental exposure conditions.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The 1-104352-4 packaging is not specified in available data. Substitute parts are supplied in bulk or tube packaging. Bulk packaging (Molex, Preci-Dip, Amphenol ICC) supports high-volume assembly operations. Samtec TD-114-T-A-1 is supplied in tube packaging, suitable for lower-volume or manual assembly processes. Packaging selection does not affect electrical or mechanical compatibility.

Q: Does the Preci-Dip 450-10-228-00-006101 circular contact shape affect compatibility?

A: Contact shape (square versus circular) affects mating force characteristics and contact pressure distribution. The Preci-Dip part features circular contacts, differing from the original square geometry. This variation may require evaluation against mating connector specifications to confirm acceptable contact engagement and retention force. The part maintains all other critical specifications including pitch, position count, and mounting type.

Q: Which substitute part offers the best regulatory compliance for new production?

A: All substitute parts achieve RoHS compliance. The Preci-Dip 450-10-228-00-006101 additionally carries REACH unaffected status, eliminating substance of concern restrictions applicable to REACH-affected parts. For applications requiring maximum regulatory alignment with current standards, the Preci-Dip part provides the most comprehensive compliance profile.

Q: Can the Samtec TD-114-T-A-1 be used as a direct substitute?

A: The Samtec part meets fundamental specifications (28 positions, 2 rows, 0.100" pitch, male pins, through-hole mounting, solder termination). However, fastening type, shrouding configuration, and contact shape parameters are not documented in available data. Confirmation against application requirements and mating connector specifications is necessary before selection.

Q: What is the impact of operating temperature range differences?

A: The original 1-104352-4 operates from -65°C to 105°C. Substitute parts offer extended ranges: Molex (not specified), Preci-Dip (-55°C ~ 125°C), and Amphenol ICC (-65°C ~ 130°C). Extended temperature ranges provide design margin for applications approaching thermal limits. For standard operating conditions within -65°C to 105°C, all substitutes perform equivalently.

Q: Are current and voltage ratings equivalent across all substitute parts?

A: The original part specifies 3A current and 30VAC voltage. Amphenol ICC parts confirm 3A per contact rating. Molex and Samtec do not specify current or voltage ratings in available documentation. Preci-Dip specifies 3A current and 150VDC voltage, exceeding original specifications. For applications requiring specific electrical ratings, confirmation against datasheet specifications is recommended.
