TE Connectivity 1-1634688-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-1634688-4 is a shrouded rectangular connector header with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This through-hole solder-terminated component features male pins with gold-plated mating contacts and tin-plated posts, designed for board-to-cable/wire applications. The part operates across -40°C to 105°C and carries a 3A current rating per contact.

The 1-1634688-4 is classified as obsolete. Equivalent and substitute parts are available from active product lines that maintain the same core electrical and mechanical specifications, enabling direct replacement in existing designs.

Substitute Part Grouping Explanation

Substitution of the 1-1634688-4 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

14 positions in 2-row configuration
0.100" (2.54mm) mating pitch and row spacing
Through-hole solder termination
Shrouded 4-wall design
Male pin contact type
Square contact shape
Push-Pull fastening mechanism
UL94 V-0 flammability rating
ROHS3 compliance

Secondary Compatibility Factors:

Contact finish materials (gold mating, tin post)
Insulation material composition
Operating temperature range

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity Active Products):

The TE Connectivity 5103308-2 and 5-87589-3 are direct substitutes from active product lines. Both maintain the core 14-position, 2-row, 0.100" pitch configuration with through-hole solder termination and shrouded 4-wall design. The 5103308-2 operates across an extended temperature range (-65°C to 105°C) compared to the original part (-40°C to 105°C) and carries a 1A per contact rating. The 5-87589-3 maintains the 3A current rating and operates across -65°C to 105°C, though it employs a Detent Lock fastening mechanism rather than Push-Pull.

Cross-Manufacturer Alternatives:

Molex C-Grid series connectors (0702461401, 0702461402, 0878341419, 0918160014) provide functionally equivalent 14-position headers with identical pitch and mounting characteristics. These parts are active products with ROHS3 compliance and UL94 V-0 flammability ratings. The 0918160014 is configured for board-to-board applications, while others support board-to-cable/wire connections.

The 3M 30314-6002HB (303 series) and Amphenol ICC 88880-349LF (Quickie™ series) are additional active alternatives meeting the same core specifications. The 3M part operates across -55°C to 105°C with a 1A current rating. All cross-manufacturer options maintain ROHS3 compliance and UL94 V-0 ratings.

Selection Basis:

All substitute parts are active products with current manufacturing support and full compliance certifications. Selection should prioritize parts matching the original current rating requirement (3A) and operating temperature range (-40°C minimum). The 5-87589-3 and TE Connectivity 5103308-2 are recommended for direct replacement due to manufacturer continuity and active product status.

Frequently Asked Questions (FAQ)

Q: Can the 5-87589-3 replace the 1-1634688-4 if the fastening mechanism differs?

A: The 5-87589-3 uses Detent Lock fastening instead of Push-Pull. While both mechanisms secure the mated connector, the physical engagement method differs. Compatibility depends on the mating connector type in the application. If the mating connector is designed for Push-Pull engagement, the Detent Lock mechanism may not provide equivalent retention.

Q: What is the significance of the current rating difference between the main part (3A) and some substitutes (1A)?

A: The 1-1634688-4 carries a 3A current rating per contact. Substitutes with lower ratings (such as 5103308-2 and 30314-6002HB at 1A) are suitable only for applications where the actual current per contact does not exceed 1A. For applications requiring the full 3A capacity, select substitutes rated at 3A, such as the 5-87589-3.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part 1-1634688-4 packaging is not specified. Substitutes are available in Tube (5103308-2), Tray (5-87589-3, 0702461401, 0878341419, 0918160014), and Bulk (0702461402, 30314-6002HB, 88880-349LF) configurations. Packaging affects order quantities and handling but does not impact electrical or mechanical compatibility.

Q: How do contact material differences affect substitution?

A: The main part uses Brass contacts, while some substitutes employ Phosphor Bronze or Copper Alloy. All materials are compatible with the specified gold mating finish and tin post finish. Contact material differences do not prevent substitution but may affect mechanical properties such as spring force and wear characteristics. For applications with high mating cycle requirements, consult material specifications.

Q: Is the operating temperature range critical for substitution?

A: The 1-1634688-4 operates from -40°C to 105°C. Substitutes with extended ranges (such as -65°C to 105°C) are fully compatible for the original temperature envelope. Substitutes with narrower ranges or unspecified ranges should be evaluated against the actual application temperature requirements.

Q: What does the keying slot feature provide?

A: The keying slot is a mechanical feature present on all listed substitutes and the main part. It prevents incorrect mating orientation by allowing the connector to mate only in the correct alignment. This feature is consistent across all alternatives.

Q: Are all substitutes RoHS compliant?

A: All listed substitutes carry either ROHS3 Compliant or RoHS Compliant status. The 88880-349LF carries RoHS Compliant status rather than ROHS3. Both designations indicate compliance with RoHS directives; ROHS3 represents the most current standard. For applications requiring ROHS3 specifically, select parts explicitly marked ROHS3 Compliant.

Q: Can the 0918160014 be used in place of the 1-1634688-4?

A: The 0918160014 is configured for board-to-board applications, while the 1-1634688-4 is designed for board-to-cable/wire connections. Although the connector geometry and pitch are identical, the intended application style differs. Substitution is possible only if the application can accommodate board-to-board mating.
