Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1842296 is the qualified substitute for the obsolete 5437091. Selection rationale is based on the following engineering factors:

Product Status: The 5437091 is classified as obsolete, while the 1842296 maintains active product status, ensuring long-term availability and continued manufacturer support.

Compliance Alignment: Both components maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. The 1842296 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS Compliant designation of the 5437091.

Electrical Performance: The 1842296 provides enhanced UL current rating (15A vs. 12A) while maintaining identical IEC ratings (10A, 400V) and UL voltage rating (300V). This represents a performance improvement with no derating requirements.

Mechanical and Electrical Compatibility: All critical mechanical parameters—pitch, position count, orientation, mounting type, contact tail length, and insulation height—are identical between the two components, ensuring direct form-fit-function replacement in existing PCB designs and connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1842296 directly replace the 5437091 in existing designs?

A: Yes. The 1842296 provides direct mechanical and electrical compatibility. All critical parameters including pitch (5.08mm), position count (20), orientation (90° right angle), mounting type (through hole), and contact specifications are identical. The enhanced UL current rating (15A vs. 12A) represents a performance improvement with no compatibility concerns.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 5437091 is obsolete and no longer manufactured. The 1842296 is an active product with ongoing manufacturer support, ensuring availability for new procurements, design revisions, and field replacements. This transition is necessary for supply chain continuity.

Q: Are there differences in compliance certifications between these parts?

A: Both components meet UL94 V-0 flammability requirements and MSL 1 (Unlimited) moisture sensitivity standards. The 1842296 carries ROHS3 compliance, representing alignment with current regulatory requirements compared to the RoHS Compliant status of the 5437091. Both maintain identical electrical safety ratings.

Q: Does the color difference (Gray vs. Green) affect electrical or mechanical function?

A: No. Color is a cosmetic parameter and does not affect electrical performance, mechanical compatibility, or functional operation. Component selection should be based on the critical parameters listed in the Parameter Comparison table.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: number of positions (20), pitch (5.08mm), header orientation (90° right angle), termination style (solder), mounting type (through hole), shrouding configuration (2 side), contact specifications (tin finish, 0.126" tail length), and electrical ratings (minimum 10A IEC, 400V IEC, 12A UL, 300V UL). The 1842296 meets all these requirements.

Q: Is the COMBICON MDSTBW series compatible with BCDH series applications?

A: Yes. Both series use identical mechanical and electrical specifications for this 20-position configuration. Series designation reflects product line organization but does not affect functional compatibility when all critical parameters match.
