Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish functional interchangeability:

Primary Substitution Criteria:

Connector type (receptacle)
Number of positions (3)
Pitch specification (0.156" / 3.96mm)
Contact type (tab)
Mounting configuration (free hanging in-line)
Contact termination method (crimp)
Fastening mechanism (latch lock)
Number of rows (1)

Secondary Considerations:

Insulation material composition
Operating temperature range
Color designation
Series classification
RoHS compliance status

All identified substitute parts maintain identical core electrical and mechanical specifications. Variations in color, insulation material formulation, operating temperature upper limits, and connector series do not affect functional compatibility when core parameters remain constant. Parts are grouped by these secondary characteristics to support application-specific requirements.

Engineering Selection Recommendations

Universal Power Series (176283 Base): Parts 176283-9, 176283-1, and 176283-2 share identical electrical and mechanical specifications with operating temperature range of -30°C to 105°C and PA66 nylon 6/6 insulation material. These parts are fully interchangeable from a functional standpoint. Selection among these variants is determined by color requirements for circuit identification or application-specific marking standards. All three maintain active product status and RoHS compliance.

Power Double Lock Series (368572 Base): Parts 368572-1, 368572-2, and 368572-9 maintain core connector specifications but operate within a reduced temperature range of -30°C to 65°C and utilize polyamide (PA) nylon material. These parts are functionally equivalent to the Universal Power series for applications operating within the -30°C to 65°C envelope. The Power Double Lock series designation indicates mechanical design differences in the fastening mechanism that do not affect housing compatibility.

Cross-Series Substitution: Parts from the Universal Power series (176283) and Power Double Lock series (368572) are interchangeable when application operating temperatures remain within -30°C to 65°C. For applications requiring operation above 65°C, only Universal Power series parts (176283-9, 176283-1, 176283-2) are suitable.

Compliance Considerations: All substitute parts maintain RoHS compliance status. Parts designated ROHS3 Compliant (176283-1, 368572-2, 368572-9) represent updated compliance certification. Parts designated RoHS Compliant (176283-9, 176283-2, 368572-1) meet baseline RoHS requirements. Both compliance levels are acceptable for applications requiring RoHS adherence.

Frequently Asked Questions (FAQ)

Q: Can 176283-9 be replaced with 368572-9?

A: Yes, for applications operating within -30°C to 65°C. Both parts maintain identical core specifications: 3-position receptacle housing, 0.156" pitch, tab contacts, crimp termination, and latch lock fastening. The primary difference is the operating temperature upper limit (105°C for 176283-9 versus 65°C for 368572-9) and connector series designation. If your application operates above 65°C, 176283-9 must be retained.

Q: What is the difference between Universal Power and Power Double Lock series?

A: Both series provide 3-position receptacle housings with identical pitch, contact type, and termination specifications. The series designation reflects internal mechanical design differences in the fastening mechanism. From a housing compatibility perspective, parts are interchangeable when operating temperature requirements are met.

Q: Are color variations functionally equivalent?

A: Yes. Black (176283-9, 368572-9), Natural (176283-1, 368572-1), and Red (176283-2, 368572-2) variants are functionally identical. Color selection is determined by application requirements for circuit identification, wiring standards, or visual marking conventions. Electrical and mechanical performance is independent of color.

Q: Can I use 176283-2 (Red) instead of 176283-9 (Black)?

A: Yes. Both parts are from the Universal Power series with identical specifications: 3-position receptacle, 0.156" pitch, -30°C to 105°C operating range, PA66 nylon 6/6 material, and RoHS compliance. Selection between them depends on color-coding requirements for your application.

Q: What is the impact of insulation material differences between PA66 and PA?

A: Parts utilizing PA66 nylon 6/6 (176283 series) and parts utilizing PA nylon (368572 series) maintain the same core connector specifications. The material difference does not affect electrical or mechanical compatibility. Material selection is determined by application environmental requirements and thermal performance needs within the specified operating temperature ranges.

Q: Are all substitute parts in active product status?

A: Yes. All identified substitute parts (176283-1, 176283-2, 368572-1, 368572-2, 368572-9) maintain active product status, indicating current manufacturing and availability. Inventory levels vary by part number and color variant.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All substitute parts carry MSL 1 rating, meaning they do not require special moisture-controlled storage or handling procedures.

Q: Can contacts from one part number be used with housings from another?

A: All substitute parts are specified as "Contacts Not Included." Contacts must be sourced separately and selected based on the specific application requirements. Compatibility between contacts and housings is determined by contact specifications and housing position design, not by housing part number.
