Key Parameters

Substitute Part Grouping Explanation

The 125SH-D-07-TR-SMT-T/R from Adam Tech qualifies as a substitute based on the following critical parameters:

• Connector Type: Header (matching)
• Contact Type: Male Pin (matching)
• Number of Positions: 7 (matching)
• Pitch - Mating: 0.049" (1.25mm) (matching)
• Mounting Type: Surface Mount, Right Angle (matching)
• Shrouding: Shrouded - 4 Wall (matching)
• Current Rating: 1A (matching)
• Material Flammability Rating: UL94 V-0 (matching)
• Termination: Solder (matching)
• Fastening Type: Push-Pull vs. Friction Lock (functional alternative)

These parameters establish mechanical and electrical compatibility for board-level interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

The 125SH-D-07-TR-SMT-T/R is an active product with current manufacturing support, addressing the obsolescence status of the DF14-7P-1.25H(26). Both connectors meet UL94 V-0 flammability requirements and maintain identical pitch, position count, and mounting configuration. The substitute part demonstrates extended lower operating temperature capability (-40°C vs. -35°C) and maintains REACH compliance and EAR99 classification. The voltage rating difference (100VAC vs. 150V) and fastening mechanism variation (Friction Lock vs. Push-Pull) require evaluation against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Are the DF14-7P-1.25H(26) and 125SH-D-07-TR-SMT-T/R mechanically interchangeable?

A: Both connectors share identical pitch (0.049" / 1.25mm), position count (7), mounting type (surface mount right-angle), and shrouding configuration (4-wall). Mechanical interchangeability is established for board-level mounting. Fastening mechanism differences (Push-Pull vs. Friction Lock) do not affect PCB mounting compatibility.

Q: What is the significance of the voltage rating difference?

A: The DF14-7P-1.25H(26) is rated for 150V while the 125SH-D-07-TR-SMT-T/R is rated for 100VAC. Applications operating at or above 100VAC require confirmation that the substitute meets voltage requirements.

Q: Does the operating temperature range difference affect substitution?

A: The 125SH-D-07-TR-SMT-T/R extends the lower temperature limit to -40°C compared to the original part's -35°C. This provides broader environmental coverage and does not restrict substitution in applications within the original temperature range.

Q: Are both parts RoHS compliant?

A: The 125SH-D-07-TR-SMT-T/R is explicitly marked as ROHS3 Compliant. The DF14-7P-1.25H(26) RoHS status is not specified in the provided data.

Q: What packaging format is available for the substitute part?

A: The 125SH-D-07-TR-SMT-T/R is supplied in Cut Tape (CT) packaging with 21,931 pieces currently in stock.
