Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors in this category is determined by strict equivalence across the following parameters:

Connector series and family: AMPMODU Mod II
Position count: 14 positions
Pitch specification: 0.100" (2.54mm) mating pitch
Contact type: Male pin configuration
Mounting method: Through-hole termination
Fastening mechanism: Push-pull
Current and temperature ratings: 3A at -65°C ~ 105°C

The substitute part 6-146277-4 maintains full electrical and mechanical compatibility across all critical parameters. Both connectors share identical pitch, position count, contact configuration, and thermal operating range. Differences in insulation material (thermoplastic vs. liquid crystal polymer) and contact finish post material (tin-lead vs. tin) do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

The 6-146277-4 is the direct substitute for the obsolete 1-102976-4. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, contact configuration, current rating, and operating temperature range.

The 6-146277-4 offers the advantage of active product status, ensuring ongoing manufacturing support and supply chain availability. Additionally, the 6-146277-4 achieves RoHS compliance, meeting current regulatory requirements for new designs and manufacturing environments with RoHS mandates.

The insulation material difference (thermoplastic in 1-102976-4 versus liquid crystal polymer in 6-146277-4) and the contact finish post material variation (tin-lead versus tin) do not impact functional interchangeability. Both materials meet the same flammability rating (UL94 V-0) and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Are the 1-102976-4 and 6-146277-4 electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications: 14 positions, 0.100" (2.54mm) pitch, male pin contacts, 3A current rating, and -65°C to 105°C operating temperature range. They are fully interchangeable in electrical function.

Q: What is the difference in insulation material between these connectors?

A: The 1-102976-4 uses thermoplastic insulation, while the 6-146277-4 uses liquid crystal polymer (LCP). Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range. LCP offers improved dimensional stability and chemical resistance in demanding environments.

Q: Does the contact finish post material difference affect compatibility?

A: No. The 1-102976-4 features tin-lead plating on the post, while the 6-146277-4 uses tin plating. Both finishes provide equivalent solderability and electrical performance. The tin finish in the 6-146277-4 aligns with current lead-free manufacturing standards.

Q: Why should I select the 6-146277-4 over the 1-102976-4?

A: The 6-146277-4 is the active product with current manufacturing support. The 1-102976-4 is obsolete and subject to supply discontinuation. Additionally, the 6-146277-4 achieves RoHS compliance, meeting regulatory requirements for new designs and manufacturing environments.

Q: Are there any mechanical mounting differences?

A: No. Both connectors use identical through-hole mounting with push-pull fastening. Physical dimensions, contact lengths, and insulation heights are identical, ensuring direct PCB footprint compatibility.

Q: What is the packaging difference?

A: The 1-102976-4 packaging is not specified in available documentation. The 6-146277-4 is supplied in bulk packaging. This difference does not affect connector function or compatibility.
