Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1824531 is determined by strict equivalence across the following critical parameters:

• 20-position configuration with 0.200" (5.08mm) pitch spacing
• Receptacle type with female socket contacts
• Screw termination methodology
• Board mount mechanical interface
• IEC electrical ratings: 12A at 630V
• UL electrical ratings: 10A at 300V
• Wire gauge acceptance: 12-30 AWG (0.2-2.5mm²)
• M3 screw specification with 0.5-0.6 Nm torque range
• Polyamide housing with UL94 V-0 flammability rating
• RoHS compliance certification

The Phoenix Contact 1824308 meets all substitution criteria as an active product within the COMBICON MSTBU series, maintaining identical electrical, mechanical, and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1824308 is the direct functional equivalent for the obsolete 1824531. Both components maintain identical electrical performance specifications under IEC and UL standards, mechanical compatibility through matching pitch and screw specifications, and equivalent compliance certifications including RoHS and UL94 V-0 flammability ratings.

The 1824308 carries active product status, ensuring ongoing availability and manufacturer support. The addition of retention latches on the 1824308 provides enhanced mechanical security without affecting electrical or dimensional compatibility with the original 1824531 design.

Selection of the 1824308 for new designs or replacement applications eliminates obsolescence risk while preserving full functional interchangeability with existing 1824531 installations.

Frequently Asked Questions (FAQ)

Q: Can the 1824308 be used as a direct replacement for the 1824531 in existing designs?

A: Yes. The 1824308 maintains identical electrical ratings (12A at 630V IEC, 10A at 300V UL), mechanical pitch (0.200"/5.08mm), screw termination specifications (M3, 0.5-0.6 Nm), and board mount interface. Both components accept 12-30 AWG wire and share identical housing material and flammability certification.

Q: What is the significance of the retention latches on the 1824308?

A: Retention latches provide mechanical locking of mated connectors. This feature does not affect electrical performance or physical compatibility with the 1824531. The latches enhance assembly security without requiring design modifications.

Q: Are there packaging differences between these parts?

A: The 1824531 was supplied in standard packaging, while the 1824308 is available in bulk packaging. Packaging format does not affect component functionality or electrical characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1824531 and 1824308 are RoHS compliant, carry UL94 V-0 flammability ratings, and maintain MSL 1 (unlimited) moisture sensitivity levels. Both are classified under ECCN EAR99 and HTSUS 8536.90.4000.

Q: Why is the 1824531 listed as obsolete?

A: Obsolescence reflects manufacturer discontinuation of production. The 1824308 represents the active continuation within the COMBICON MSTBU series, offering equivalent functionality with enhanced features and ongoing supply availability.
