Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector type (Receptacle)
• Number of positions (3)
• Pitch specification (0.236" / 6.00mm)
• Contact type (Tab)
• Contact termination method (Crimp)
• Fastening type (Latch Lock)
• Operating temperature range (-55°C ~ 105°C)
• Insulation material composition (Polybutylene Terephthalate)

The substitute part 1-1971772-3 meets all primary substitution criteria. The key distinction between the main part and its substitute is the mounting type: the 1-1971771-3 is configured for free-hanging, in-line mounting, while the 1-1971772-3 is designed for panel mount, snap-in applications. Both housings accommodate identical contact specifications and operate within the same electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1-1971772-3 is the primary substitute for the obsolete 1-1971771-3. This substitute maintains electrical and thermal compatibility while offering the advantage of active product status, ensuring continued availability and supply chain support.

The 1-1971772-3 is RoHS Compliant and REACH Unaffected, providing regulatory compliance advantages over the main part, which has undefined REACH status. The glass-filled PBT insulation material in the substitute offers enhanced mechanical properties compared to standard PBT.

Selection of the 1-1971772-3 requires evaluation of the mounting configuration. The substitute's panel mount, snap-in design differs from the free-hanging, in-line mounting of the original part. Applications requiring in-line mounting must accommodate this mechanical difference through appropriate board layout or connector assembly modifications.

Both parts share identical contact accommodation specifications, pitch, and fastening mechanisms, ensuring that crimp-terminated contacts and mating connectors remain compatible.

Frequently Asked Questions (FAQ)

Q: Can the 1-1971772-3 directly replace the 1-1971771-3 in existing assemblies?

A: Electrical and thermal compatibility is maintained. However, the mounting type differs: the 1-1971771-3 is free-hanging, in-line, while the 1-1971772-3 is panel mount, snap-in. Physical integration into the assembly must be evaluated based on the specific application's mounting requirements.

Q: Are the contact specifications identical between these two housings?

A: Yes. Both housings accommodate 3-position, tab-type contacts with crimp termination and latch lock fastening. Contacts specified for the 1-1971771-3 are compatible with the 1-1971772-3 housing.

Q: What is the significance of the glass-filled PBT material in the 1-1971772-3?

A: Glass-filled PBT provides improved mechanical strength and dimensional stability compared to standard PBT. This enhancement does not affect electrical performance or thermal operating range but offers greater robustness in mechanical stress conditions.

Q: Why is the 1-1971771-3 classified as obsolete?

A: The 1-1971771-3 is no longer in active production. The 1-1971772-3 represents the current active equivalent within the Power Triple Lock Standard series.

Q: Are there regulatory compliance differences between these parts?

A: The 1-1971772-3 carries explicit RoHS Compliance and REACH Unaffected certifications. The 1-1971771-3 has undefined REACH status. Both are classified as EAR99 for export control purposes.

Q: What is the inventory status of these parts?

A: The 1-1971771-3 has 1019 pieces in stock as new original inventory. The 1-1971772-3 has 1125 pieces in stock, packaged in bulk. Availability should be confirmed with the supplier for current requirements.

Q: Can these connectors be used in high-temperature applications?

A: Both housings operate across -55°C to 105°C. Applications requiring operation at the upper or lower limits of this range are within specification for both parts.
