Phoenix Contact 1735639 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1735639 is a 9-position terminal block header with male pins, shrouded on four sides, designed for 90° right-angle through-hole mounting. This component operates at 12A (IEC) and 250V (IEC), featuring 0.197" (5.00mm) pitch spacing and tin-plated contacts. The part belongs to the COMBICON MSTBA series and carries RoHS Compliant certification with MSL 1 rating.

The 1735639 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1735639 is determined by strict alignment of the following core parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (12A IEC, 250V IEC minimum)
• Physical Compatibility: Number of positions (9), pitch spacing (0.197" / 5.00mm), header orientation (90° right angle), and mounting type (through hole) must be identical
• Connector Type: Male pins with four-side shrouding are required
• Termination Method: Solder termination is mandatory
• Regulatory Compliance: RoHS Compliant status and MSL 1 rating must be maintained

The Phoenix Contact 1836641 qualifies as a direct substitute based on these criteria. Both components share identical mechanical and electrical interface specifications while differing in series designation (COMBICON CCA versus COMBICON MSTBA) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1836641 is the qualified substitute for the obsolete 1735639 based on the following engineering criteria:

Electrical Performance: The 1836641 exceeds the original electrical specifications. It maintains the 12A IEC current rating while increasing voltage capacity from 250V to 400V (IEC). UL certification provides additional 16A (UL) and 300V (UL) ratings, offering enhanced performance margins for applications requiring North American compliance.

Mechanical Compatibility: Both components maintain identical mechanical interfaces—9 positions, 5.00mm pitch, 90° right-angle orientation, and through-hole mounting. Physical interchangeability is confirmed.

Regulatory Compliance: Both parts carry RoHS Compliant certification and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and handling requirements.

Product Lifecycle: The 1836641 holds Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 1735639.

Material Specification: The 1836641 specifies Liquid Crystal Polymer (LCP) housing material with UL94 V-0 flammability rating, providing enhanced material performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1836641 be used as a direct replacement for the 1735639 in existing designs?

A: Yes. Both components share identical electrical interface specifications (12A IEC, 9 positions, 5.00mm pitch, 90° right angle, solder termination, through-hole mounting). The 1836641 meets or exceeds all electrical and mechanical requirements of the original part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (1735639 is obsolete; 1836641 is active), series designation (MSTBA versus CCA), voltage rating (250V IEC versus 400V IEC), and housing material specification (1836641 specifies LCP with UL94 V-0 rating). The 1836641 also includes UL certification data (16A, 300V).

Q: Are there packaging differences between the 1735639 and 1836641?

A: The 1735639 packaging is not specified in the available data. The 1836641 is supplied in Tape & Reel (TR) packaging format.

Q: Do both parts carry the same certifications?

A: Both parts are RoHS Compliant with MSL 1 (Unlimited) rating. The 1836641 additionally carries UL94 V-0 material flammability certification and UL electrical ratings (16A, 300V).

Q: Is the 1836641 suitable for applications originally designed for 250V operation?

A: Yes. The 1836641 operates at 400V (IEC), which exceeds the original 250V requirement. It is suitable for any application within the original voltage specification.
