Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-5331677-3 is the direct equivalent for the obsolete 1-331677-3. Selection of the substitute is based on the following factors:

Product Status: The main part 1-331677-3 carries an obsolete designation, making the active status of 1-5331677-3 the appropriate choice for new designs and ongoing procurement.

Regulatory Compliance: The substitute part 1-5331677-3 is RoHS Compliant, whereas the main part is RoHS non-compliant. This represents an improvement in environmental and regulatory alignment for applications subject to RoHS requirements.

Functional Equivalence: All mechanical and electrical parameters are identical between the two parts, including pin diameter acceptance, termination method, contact material, contact finish, and operating temperature range. The substitute operates at a marginally higher maximum temperature (126°C versus 125°C), which presents no compatibility concerns.

Availability: The substitute part 1-5331677-3 is available in active inventory status with 1173 pieces in stock, compared to the obsolete main part with 821 pieces.

Frequently Asked Questions (FAQ)

Q: Can 1-5331677-3 be used as a direct replacement for 1-331677-3 in existing assemblies?

A: Yes. The substitute part 1-5331677-3 maintains identical mechanical and electrical specifications across all critical parameters, including pin diameter acceptance (0.030" ~ 0.033"), solder termination, overall length (0.138"), mounting hole diameter (0.062" ~ 0.063"), flange diameter (0.080"), socket depth (0.125"), contact material (Beryllium Copper), contact finish (Tin), and closed bottom feature. The parts are functionally interchangeable.

Q: What is the difference in operating temperature range between these parts?

A: The main part 1-331677-3 operates from -65°C to 125°C, while the substitute 1-5331677-3 operates from -65°C to 126°C. This 1°C difference at the upper limit does not affect compatibility or performance in standard applications.

Q: Does the RoHS compliance difference affect substitution?

A: The substitute part 1-5331677-3 is RoHS Compliant, while the main part 1-331677-3 is RoHS non-compliant. For applications subject to RoHS regulations, the substitute provides improved compliance. For applications without RoHS requirements, this difference does not affect functional compatibility.

Q: Are there packaging differences between these parts?

A: The main part 1-331677-3 does not specify packaging details, while the substitute 1-5331677-3 is supplied in Bulk packaging. Both parts are identical in form, fit, and function.

Q: What contact material and finish are used in both parts?

A: Both parts use Beryllium Copper as the contact material with a Tin finish applied to a thickness of 100.0µin (2.54µm). This ensures consistent electrical performance and reliability.

Q: Can these parts accept different pin diameters?

A: No. Both parts accept identical pin diameters in the range of 0.030" to 0.033" (0.76mm to 0.84mm). Pins outside this range will not fit properly.

Q: What is the significance of the "Closed Bottom" feature?

A: The closed bottom feature is present in both parts and prevents solder or contaminants from entering the socket from the rear during assembly and operation, ensuring reliable electrical contact and mechanical integrity.
