Phoenix Contact 0708137 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0708137 is a 4-position terminal block header from the COMBICON DFK-MSTB series, designed for front panel male pin connections with rear panel quick connect solder eyelet termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The part operates at 300V UL with a 10A current rating and features screw mount front flange installation with lock opening functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 0708137 is based on strict electrical and mechanical parameter matching within the COMBICON DFK-MSTB series. The substitute part 0707125 maintains identical specifications across all critical dimensions and connection interfaces: 4-position configuration, 5.00mm pitch, 40.00mm width, screw mount front flange, and quick connect solder eyelet rear termination. Both parts support the same panel thickness range (0.5 ~ 4.0mm) and feature lock opening functionality.

The primary distinction between these parts is product status and current rating. The 0708137 is obsolete with a 10A UL current rating, while the 0707125 is active production with an enhanced 15A UL current rating. This increased current capacity in the substitute part provides superior electrical performance while maintaining full mechanical and dimensional compatibility. Both parts are RoHS compliant and carry MSL rating 1 (unlimited moisture sensitivity).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 0707125 is the direct active production equivalent for the obsolete 0708137. Both parts are manufactured by Phoenix Contact within the same COMBICON DFK-MSTB series and share identical mechanical and dimensional specifications. The 0707125 is ROHS3 compliant, representing current regulatory compliance standards, while the 0708137 carries RoHS compliance from an earlier standard generation.

The 0707125 provides enhanced electrical performance with a 15A UL current rating compared to the 0708137's 10A rating, while maintaining all other electrical parameters at 300V UL. This increased current capacity ensures the substitute part meets or exceeds the requirements of applications originally designed for the 0708137.

For new designs and production continuity, the 0707125 should be specified. For legacy system maintenance where the original 0708137 is no longer available, the 0707125 provides full functional and mechanical compatibility with improved electrical performance and current regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 0707125 be used as a direct replacement for the 0708137 in existing applications?

A: Yes. Both parts are mechanically and electrically compatible. They share identical dimensions (40.00mm width, 5.00mm pitch), panel mount configuration (screw mount front flange), connection interfaces (male pin header front, quick connect solder eyelet rear), and voltage rating (300V UL). The 0707125 provides enhanced current capacity (15A vs. 10A), making it suitable for applications originally designed for the 0708137.

Q: What is the significance of the current rating difference between these parts?

A: The 0708137 is rated for 10A UL current, while the 0707125 is rated for 15A UL current. Both operate at 300V UL. The higher current rating of the 0707125 indicates improved electrical performance and thermal characteristics, allowing it to safely handle higher current loads while maintaining the same voltage specification.

Q: Are there packaging differences between these parts?

A: The 0708137 is supplied in standard packaging, while the 0707125 is supplied in bulk packaging. This difference affects order quantities and handling but does not impact electrical or mechanical compatibility.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate RoHS compliance. ROHS3 represents compliance with the current RoHS 3 directive (2011/65/EU as amended), while RoHS indicates compliance with earlier RoHS standards. The 0707125's ROHS3 compliance ensures alignment with current regulatory requirements.

Q: Are both parts suitable for the same panel thickness applications?

A: Yes. Both the 0708137 and 0707125 support the same panel thickness range of 0.020 ~ 0.157" (0.5 ~ 4.0mm) with screw mount front flange installation.

Q: What does the lock opening feature provide?

A: Lock opening is a mechanical feature present on both parts that provides secure connection retention and prevents accidental disconnection during operation.
