Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-177899-1 is determined by strict equivalence across the following critical parameters: connector type (plug), contact type (female socket), number of positions (3), pitch (0.156"/3.96mm), number of rows (1), mounting type (free hanging inline), contact termination method (crimp), and fastening mechanism (latch lock). These parameters define the mechanical and electrical interface compatibility.

Two substitute parts are identified:

Direct Manufacturer Equivalent (368571-1): Maintains identical specifications across all critical parameters. Differs only in product status (active versus obsolete) and packaging format (bulk). This part provides direct functional replacement with enhanced procurement availability.

Parametric Equivalent (176272-4): Maintains identical specifications across all critical parameters except color (yellow versus natural) and connector series designation (Universal Power versus Power Double Lock). This part provides functional compatibility with visual differentiation through color coding.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Part 368571-1 is the primary substitute for the obsolete 5-177899-1. This part maintains complete parametric equivalence and is currently in active production status with substantial inventory availability (131,212 pieces). Both parts meet RoHS compliance requirements and share identical electrical and mechanical interface specifications. The transition from obsolete to active status ensures long-term procurement viability.

For Color-Coded Applications: Part 176272-4 provides functional equivalence with yellow color differentiation. This part is suitable for applications requiring visual circuit identification or color-coded connector systems. The part maintains active production status and meets ROHS3 compliance. The Universal Power series designation indicates compatibility with broader connector ecosystem applications while preserving all critical mechanical and electrical parameters.

Compliance Considerations: All three parts maintain MSL Level 1 (unlimited moisture sensitivity) classification and EAR99 export control designation. The 368571-1 carries RoHS Compliant status while 5-177899-1 and 176272-4 carry ROHS3 Compliant status. Selection should account for specific regulatory requirements within the target application environment.

Frequently Asked Questions (FAQ)

Q: Can 368571-1 directly replace 5-177899-1 in existing designs?

A: Yes. Part 368571-1 maintains identical specifications across all critical parameters: 3-position plug housing, 0.156" pitch, female socket contacts, crimp termination, latch lock fastening, and free-hanging inline mounting. The parts are mechanically and electrically interchangeable.

Q: What is the primary difference between 368571-1 and 176272-4?

A: The primary difference is color: 368571-1 is natural (matching the original 5-177899-1), while 176272-4 is yellow. Both parts maintain identical electrical and mechanical specifications. Secondary differences include series designation (Power Double Lock versus Universal Power) and insulation material documentation.

Q: Is 176272-4 suitable for applications requiring natural-colored connectors?

A: No. Part 176272-4 is yellow and is intended for applications requiring color-coded connector identification. For natural-colored connector requirements, use 368571-1.

Q: What are the packaging differences between these parts?

A: The original 5-177899-1 packaging format is not specified in available documentation. Both substitute parts (368571-1 and 176272-4) are supplied in bulk packaging format.

Q: Are there operating temperature specifications for the original part?

A: Operating temperature is not specified for 5-177899-1. Both substitute parts operate across -30°C to 105°C range, which represents the standard operating envelope for this connector family.

Q: Do these parts include contacts?

A: No. All three parts (5-177899-1, 368571-1, and 176272-4) are connector housings only. Contacts must be procured separately and crimped into the housing.

Q: What is the inventory status for procurement?

A: Part 5-177899-1 (obsolete) has 1,031 pieces available. Part 368571-1 (active) has 131,212 pieces available. Part 176272-4 (active) has 19,783 pieces available. For new designs, 368571-1 or 176272-4 are recommended due to active production status.

Q: Are all parts RoHS compliant?

A: Yes. Part 5-177899-1 is ROHS3 Compliant. Part 368571-1 is RoHS Compliant. Part 176272-4 is ROHS3 Compliant. All parts meet RoHS requirements for lead-free and restricted substance compliance.
