DF14-4P-1.25H(26) Equivalent & Substitute Parts

Part Overview

The DF14-4P-1.25H(26) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 4 positions at 0.049" (1.25mm) pitch. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The connector features shrouded 4-wall construction with solder termination and push-pull fastening, suitable for board-to-cable/wire interconnections in applications requiring 1A current capacity at 150V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF14-4P-1.25H(26) is determined by the following critical parameters:

• Pitch - Mating: 0.049" (1.25mm) — must match exactly
• Number of Positions: 4 — must match exactly
• Mounting Type: Surface Mount, Right Angle — must match exactly
• Shrouding: Shrouded - 4 Wall — must match exactly
• Connector Type: Header — must match exactly
• Contact Type: Male Pin — must match exactly
• Termination: Solder — must match exactly
• Current Rating: 1A — must match or exceed
• Voltage Rating: 150V — must match or exceed
• Operating Temperature Range: -35°C ~ 85°C — must encompass or match
• Material Flammability Rating: UL94 V-0 — must match or exceed

Two substitute parts meet these criteria with varying degrees of parameter alignment.

Parameter Comparison

Engineering Selection Recommendations

DF14-4P-1.25H(22) is the primary substitute for the obsolete DF14-4P-1.25H(26). Both components are manufactured by Hirose Electric Co Ltd within the same DF14 series and share identical electrical and mechanical specifications. The DF14-4P-1.25H(22) is active in production with significantly higher inventory availability (3509 units). The contact finish differs (Tin versus Tin-Copper), and the DF14-4P-1.25H(22) carries ROHS3 compliance versus RoHS compliance on the original part. Voltage rating is specified as 150VAC on the substitute versus 150V on the original. This part is recommended for direct replacement in new designs and production continuity.

125SH-D-04-TR-SMT-T/R by Adam Tech is an alternative substitute meeting core dimensional and electrical requirements. This part maintains the 0.049" (1.25mm) pitch, 4-position configuration, surface mount right-angle mounting, and shrouded 4-wall construction. However, the following differences require engineering evaluation: fastening type is Friction Lock rather than Push-Pull; contact shape is Rectangular rather than Square; insulation height is 0.134" (3.40mm) versus 0.098" (2.50mm); insulation material is Thermoplastic rather than Polyamide (PA), Nylon; and voltage rating is 100VAC versus 150V. The 125SH-D-04-TR-SMT-T/R is active in production with the highest inventory availability (11291 units) and carries ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can DF14-4P-1.25H(22) be used as a direct replacement for DF14-4P-1.25H(26)?

A: Yes. Both parts share identical pitch (0.049" / 1.25mm), position count (4), mounting type (surface mount right-angle), shrouding (4-wall), termination (solder), current rating (1A), operating temperature range (-35°C ~ 85°C), and flammability rating (UL94 V-0). The DF14-4P-1.25H(22) is active in production and recommended for replacement applications.

Q: What are the key differences between DF14-4P-1.25H(22) and 125SH-D-04-TR-SMT-T/R?

A: The primary differences are: fastening mechanism (Push-Pull versus Friction Lock), contact shape (Square versus Rectangular), insulation height (0.098" versus 0.134"), insulation material (Polyamide/Nylon versus Thermoplastic), and voltage rating (150VAC versus 100VAC). Both maintain the critical 1.25mm pitch and 4-position configuration.

Q: Is the 125SH-D-04-TR-SMT-T/R suitable for applications requiring 150V operation?

A: The 125SH-D-04-TR-SMT-T/R is rated for 100VAC. Applications requiring 150V operation should use DF14-4P-1.25H(22), which is rated for 150VAC.

Q: What packaging options are available for these substitutes?

A: DF14-4P-1.25H(22) is supplied in Tape & Reel (TR) packaging. 125SH-D-04-TR-SMT-T/R is supplied in Cut Tape (CT) packaging. Packaging selection depends on production volume and assembly line requirements.

Q: Are all three parts RoHS compliant?

A: The original DF14-4P-1.25H(26) is RoHS Compliant. Both substitutes, DF14-4P-1.25H(22) and 125SH-D-04-TR-SMT-T/R, are ROHS3 Compliant, which represents a more current compliance standard.
