Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1687888 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Phoenix Contact
• Series: HEAVYCON® B10
• Connector Type: Insert
• Gender: Female
• Size: B10
• Voltage Rating: 600V
• Housing Material: Polycarbonate (PC)
• Contact Material: Copper Alloy
• Contact Finish: Silver
• Operating Temperature Range: -40°C ~ 125°C
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Criteria:

• RoHS Compliance Status
• Moisture Sensitivity Level (MSL)

The substitute part 1407729 maintains compatibility across all primary criteria. Variations in termination style (tension clamp versus push in) and position count (10 versus 10+ground) represent functional enhancements rather than incompatibilities, as both configurations operate within the same electrical and mechanical envelope of the B10 series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1407729 is the designated substitute for the obsolete 1687888 within the HEAVYCON® B10 series. Both components share identical electrical ratings (600V), thermal operating range (-40°C ~ 125°C), and material specifications (polycarbonate housing, copper alloy contacts with silver finish, UL94 V-0 flammability rating).

The 1407729 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component maintains full RoHS3 compliance, exceeding the RoHS compliance level of the original part. Both components carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

The termination style difference (push in versus tension clamp) and the addition of a ground position in the 1407729 represent design enhancements compatible with B10 series mechanical and electrical specifications. The 1407729 specifies a 13A current rating, providing defined electrical performance characteristics for applications requiring this parameter.

Frequently Asked Questions (FAQ)

Q: Can the 1407729 directly replace the 1687888 in existing assemblies?

A: Yes. Both components are female inserts within the HEAVYCON® B10 series with identical voltage ratings (600V), temperature ranges (-40°C ~ 125°C), housing materials (polycarbonate), and contact specifications (copper alloy with silver finish). The mechanical envelope and electrical interface are compatible.

Q: What is the significance of the termination style difference between tension clamp and push in?

A: Termination style refers to the method of wire attachment to the contact. Tension clamp and push in are distinct termination technologies within the B10 series. Selection depends on application-specific wiring requirements and assembly procedures. Both styles maintain compatibility with the B10 connector housing and mating interfaces.

Q: Why does the 1407729 include a ground position while the 1687888 specifies 10 positions?

A: The 1407729 is configured as 10+Ground, providing an additional dedicated ground contact. This represents a functional enhancement within the B10 series envelope. Applications requiring only 10 signal positions can utilize the 1407729 without the ground contact, or select the ground contact as needed for system grounding requirements.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS compliant. The 1407729 carries ROHS3 compliance designation, representing current regulatory alignment. Both components maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. The 1407729 includes REACH Unaffected status documentation.

Q: What is the inventory status for these components?

A: The 1687888 (obsolete) has 770 pieces in stock. The 1407729 (active) has 728 pieces in stock. As an active product, the 1407729 maintains ongoing manufacturing and supply availability.

Q: Are there any electrical performance differences?

A: The 1407729 specifies a 13A current rating. The 1687888 does not provide a current rating specification. Both components operate at 600V voltage rating and -40°C ~ 125°C temperature range. Application-specific current requirements should be evaluated against the 1407729 specification.
