The identified substitutes maintain electrical performance, mechanical compatibility, and regulatory compliance while offering active product status and alternative termination methods.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1757381 (COMBICON MSTBA Series)

Part 1757381 is the primary substitute for the obsolete 1880449. Both components maintain identical electrical specifications (12A IEC, 400V IEC, 15A UL, 300V UL), mechanical configuration (16 positions, 5.08mm pitch, 90° right-angle through-hole), and regulatory compliance (UL94 V-0, RoHS3 Compliant). The primary difference is termination method: 1757381 uses solder termination versus the original press-fit design. Housing material differs (Polyamide/Nylon versus PBT), but both materials meet flammability requirements. Active product status ensures long-term availability and supply chain continuity. Contact tail length is reduced (4.60mm versus 4.19mm), requiring PCB layout verification for through-hole depth compatibility.

Phoenix Contact 1827676 (COMBICON CCA Series)

Part 1827676 serves as a secondary substitute for applications operating at reduced voltage levels (250V IEC maximum). This component maintains 16-position configuration, 5.08mm pitch, 90° right-angle orientation, and 12A IEC current rating. Electrical performance is suitable for systems not requiring 400V IEC operation. Housing material is Liquid Crystal Polymer (LCP), providing enhanced thermal and chemical resistance compared to PBT. Solder termination and active product status align with 1757381. Insulation height (8.56mm) and contact tail length (2.60mm) differ from the original, requiring mechanical envelope validation. Color is black rather than green, which may impact visual identification in legacy systems.

Selection Criteria:

• For direct replacement in 400V IEC systems: Select 1757381
• For reduced-voltage applications (≤250V IEC): 1827676 is acceptable
• Verify PCB through-hole depth accommodates reduced contact tail lengths (4.60mm or 2.60mm)
• Confirm solder termination compatibility with existing assembly processes
• Validate housing material compatibility with operating environment and thermal requirements

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1757381 directly replace the obsolete 1880449 in existing designs?

A: Yes, 1757381 is electrically and mechanically compatible for direct substitution in applications requiring 400V IEC operation. The primary consideration is termination method: 1757381 uses solder termination instead of press-fit. PCB layout must accommodate the reduced contact tail length (4.60mm versus 4.19mm). Both components maintain identical pitch (5.08mm), position count (16), orientation (90° right-angle), and electrical ratings (12A IEC, 400V IEC).

Q: What is the key difference between 1757381 and 1827676?

A: The primary difference is maximum voltage rating: 1757381 supports 400V IEC, while 1827676 is rated for 250V IEC maximum. Both maintain 12A IEC current rating and 16-position configuration. Housing materials differ (Polyamide/Nylon versus Liquid Crystal Polymer), and contact tail lengths vary (4.60mm versus 2.60mm). Select 1827676 only for applications not exceeding 250V IEC operation.

Q: Are there packaging differences between the main part and substitutes?

A: The original 1880449 was supplied in unspecified packaging. Substitutes 1757381 and 1827676 are supplied in bulk packaging. Inventory availability differs: 1880449 (728 pcs), 1757381 (840 pcs), 1827676 (748 pcs). Bulk packaging may require adjustment to procurement and storage procedures.

Q: Do the substitutes maintain RoHS compliance?

A: Yes. The original 1880449 is RoHS Compliant. Substitute 1757381 is ROHS3 Compliant (enhanced standard). Substitute 1827676 is RoHS Compliant. All three components meet regulatory requirements for restricted substance elimination.

Q: What is the impact of housing material changes on performance?

A: The original 1880449 uses Polybutylene Terephthalate (PBT). Substitute 1757381 uses Polyamide (PA)/Nylon, and 1827676 uses Liquid Crystal Polymer (LCP). All materials meet UL94 V-0 flammability requirements. Material selection affects thermal stability, chemical resistance, and mechanical properties. Polyamide offers good mechanical strength and cost efficiency. LCP provides superior thermal and chemical resistance. Selection depends on operating environment and thermal requirements.

Q: Are contact tail length variations critical for PCB compatibility?

A: Yes. Contact tail length directly affects through-hole depth requirements. Original 1880449: 0.165" (4.19mm). Substitute 1757381: 0.138" (4.60mm). Substitute 1827676: 0.102" (2.60mm). PCB design must accommodate the selected component's tail length. Shorter tail lengths may require design modification or validation that existing through-hole depth is sufficient for reliable solder joint formation.

Q: Can 1827676 be used in 400V IEC applications?

A: No. Part 1827676 is rated for 250V IEC maximum. Use in applications exceeding 250V IEC violates component specifications and creates safety and reliability risks. For 400V IEC operation, select 1757381.
