Phoenix Contact 1915880 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915880 is a 17-position terminal block header with male pins, shrouded on four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON EMSTBV series and carries an obsolete product status. The part operates at 12A current (IEC/UL) and 320V (IEC) / 300V (UL) voltage ratings with press-fit termination. Due to its obsolete classification, equivalent substitute parts with active product status are available to maintain design continuity and ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915880 is determined by strict alignment with the following core parameters:

• Position Count & Pitch: All substitutes must maintain 17 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type & Orientation: Substitutes must be male pin headers with four-side shrouding in vertical orientation to match the original form factor and mounting footprint.
• Mounting Technology: Through-hole mounting is required; substitutes may employ either press-fit or solder termination styles, as both are compatible with through-hole PCB assembly.
• Electrical Ratings: Substitutes must meet or exceed the 12A current rating and maintain voltage ratings compatible with the application (minimum 300V UL / 320V IEC).
• Flammability Compliance: All substitutes must carry UL94 V-0 material flammability rating to maintain safety and regulatory compliance.

The two identified substitutes (1755888 and 1827922) satisfy all mandatory parameters while offering active product status and improved material specifications.

Parameter Comparison

Engineering Selection Recommendations

Part 1755888 (COMBICON MSTBVA Series) is the primary substitute candidate. It maintains identical position count, pitch, shrouding configuration, and through-hole mounting. The termination style transitions from press-fit to solder, which is compatible with standard PCB assembly processes. The IEC voltage rating increases to 630V, providing enhanced margin above the original 320V specification. Housing material changes from PBT to polyamide (PA/nylon), and the part carries active product status with RoHS compliance, ensuring long-term availability and regulatory alignment.

Part 1827922 (COMBICON CCVA Series) serves as an alternative substitute with identical core mechanical and electrical parameters. This part features liquid crystal polymer (LCP) housing material, which offers superior thermal and chemical resistance compared to PBT. The contact tail length is reduced to 0.102" (2.60mm) versus the original 0.154" (3.90mm), which may require PCB layout verification to confirm compatibility with existing through-hole pad spacing. The IEC voltage rating of 250V meets the minimum requirement but provides less margin than the original specification. This part also carries active product status and RoHS compliance.

Both substitutes are suitable for applications requiring the original 1915880 functionality. Selection between 1755888 and 1827922 should be based on specific PCB layout constraints (contact tail length) and material performance requirements (thermal/chemical resistance).

Frequently Asked Questions (FAQ)

Q: Can the 1755888 substitute directly replace the 1915880 in existing designs?

A: Yes. The 1755888 maintains identical position count (17), pitch (0.200"/5.08mm), shrouding configuration (4-side), orientation (vertical), and through-hole mounting. The termination style change from press-fit to solder is compatible with standard PCB assembly. Electrical ratings meet or exceed the original specification (630V IEC vs. 320V IEC). No PCB layout modifications are required.

Q: What is the key difference between the 1755888 and 1827922 substitutes?

A: The primary difference is contact tail length: 1755888 maintains the original 0.154" (3.90mm) tail length, while 1827922 reduces this to 0.102" (2.60mm). This affects through-hole pad depth compatibility. Additionally, 1827922 uses liquid crystal polymer (LCP) housing versus polyamide (PA) in the 1755888, offering different thermal and chemical performance profiles. Both maintain identical position count, pitch, and electrical ratings.

Q: Why does the 1915880 have obsolete product status?

A: Obsolete status indicates the part is no longer manufactured or supported by Phoenix Contact. The identified substitutes (1755888 and 1827922) are active products with current manufacturing support, ensuring design continuity and supply chain reliability for new applications or design refreshes.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 1755888 and 1827922 carry RoHS Compliant status, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances. The original 1915880 does not specify RoHS compliance status.

Q: What is the voltage rating difference between the substitutes?

A: The 1755888 provides 630V IEC rating, significantly exceeding the original 320V specification. The 1827922 provides 250V IEC rating, which meets the minimum requirement but offers less margin. For applications requiring maximum voltage headroom, 1755888 is the preferred choice.

Q: Can I use the 1827922 if my PCB layout is designed for the original 0.154" contact tail length?

A: No. The 1827922 contact tail length of 0.102" (2.60mm) is shorter than the original 0.154" (3.90mm). This may result in insufficient solder joint depth or mechanical engagement with the PCB through-hole. PCB layout verification and potential redesign would be required. The 1755888 maintains the original tail length and is recommended for existing PCB designs.
