Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-1971771-3 is determined by strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Connector type: Receptacle
• Number of positions: 3
• Pitch: 0.236" (6.00mm)
• Contact type: Tab
• Contact termination: Crimp
• Fastening type: Latch Lock
• Series: Power Triple Lock, High Temp

The substitute part 5-1971772-3 maintains all core compatibility parameters. Differences exist in mounting type (panel mount, snap-in versus free hanging in-line), insulation material composition (polyamide/nylon versus polybutylene terephthalate), operating temperature upper limit (150°C versus 105°C), and product status (active versus obsolete). These differences do not prevent functional substitution when mounting configuration and thermal requirements are compatible with the application.

Parameter Comparison

Engineering Selection Recommendations

The 5-1971772-3 serves as the active equivalent for the obsolete 5-1971771-3. Both parts share identical core electrical and mechanical specifications within the Power Triple Lock, High Temp series, including 3-position configuration, 6.00mm pitch, tab contact type, crimp termination, and latch lock fastening.

Selection of the 5-1971772-3 is supported by its active product status, ensuring ongoing availability and manufacturing support. The substitute part provides an extended operating temperature range (-55°C ~ 150°C) compared to the original part (-55°C ~ 105°C), offering enhanced thermal capability for demanding applications.

The primary design consideration is mounting configuration: the substitute part features panel mount, snap-in mounting, whereas the original part is free hanging in-line. Applications requiring free hanging in-line mounting must evaluate whether panel mount, snap-in configuration is compatible with the mechanical assembly design.

The substitute part carries RoHS Compliance certification, whereas the original part status is not specified. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation.

Frequently Asked Questions (FAQ)

Q: Can the 5-1971772-3 directly replace the 5-1971771-3 in all applications?

A: The 5-1971772-3 maintains electrical and contact compatibility with the 5-1971771-3 through identical pitch, position count, contact type, and termination method. The primary consideration is mounting configuration: the substitute uses panel mount, snap-in mounting versus the original free hanging in-line design. Applications must confirm mechanical compatibility with the mounting type change.

Q: What is the significance of the insulation material difference between the parts?

A: The original part uses Polybutylene Terephthalate (PBT) insulation, while the substitute uses Polyamide (PA) and Nylon. Both materials are suitable for the operating temperature ranges specified for each part. The substitute's polyamide composition supports the extended upper temperature limit of 150°C.

Q: Does the extended operating temperature range of the 5-1971772-3 affect compatibility?

A: The substitute part's extended operating temperature range (-55°C ~ 150°C) compared to the original (-55°C ~ 105°C) does not reduce compatibility. Applications operating within the original temperature range remain fully compatible. Applications requiring operation above 105°C benefit from the substitute's enhanced thermal capability.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute part is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it relates to order quantity and handling procedures.

Q: What compliance certifications apply to the substitute part?

A: The 5-1971772-3 carries RoHS Compliance certification. Both the original and substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation. REACH status for the substitute is listed as vendor undefined.

Q: Are contacts included with either part?

A: Contacts are not included with either the 5-1971771-3 or the 5-1971772-3. Both parts are connector housings only and require separate procurement of compatible crimp contacts.
