TE Connectivity AMP Connectors 1546931-9 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1546931-9 is a 9-position terminal block header featuring male pins in an unshrouded configuration with 0.197" (5.00mm) vertical pitch. This component is designed for through-hole solder termination applications and is classified as Active product status. The Buchanan series header operates at 300 V UL and 12 A UL current rating with UL94 V-0 flammability compliance. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility permits component selection from multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution of the TE Connectivity 1546931-9 are:

Critical Matching Parameters:

• Number of positions: 9
• Pitch: 0.197" (5.00mm)
• Header orientation: Vertical
• Type: Header, Male Pins, Unshrouded
• Termination style: Solder
• Mounting type: Through Hole
• Contact tail length: 0.138" (3.50mm)
• Insulation height: 0.079" (2.00mm)

Electrical Compatibility Parameters:

• Voltage rating: 300 V UL minimum
• Current rating: 12 A UL minimum
• Material flammability: UL94 V-0

The Phoenix Contact 1933257 satisfies all critical matching parameters and exceeds electrical requirements with 16 A UL current rating and 400 V IEC voltage rating. Both parts maintain identical physical dimensions and solder termination methodology, enabling direct substitution in applications requiring 9-position, 5mm-pitch vertical terminal block headers.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1546931-9 and Phoenix Contact 1933257 are Active product status components with full regulatory compliance. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

TE Connectivity 1546931-9 is suitable for applications requiring the Buchanan series specification with 12 A UL current and 300 V UL voltage ratings. This part maintains RoHS compliance and MSL 1 moisture sensitivity classification.

Phoenix Contact 1933257 provides equivalent functionality within the COMBICON PST series with enhanced electrical ratings of 16 A UL and 400 V IEC voltage. This part meets ROHS3 compliance and REACH Unaffected status, offering additional regulatory flexibility. The higher current rating provides design margin in applications approaching the 12 A specification limit.

Both components feature identical mechanical dimensions, solder termination methodology, and flammability ratings, enabling direct substitution without PCB redesign or mechanical rework.
