DF1B-12P-2.5DS(01) Equivalent & Substitute Parts

Part Overview

The DF1B-12P-2.5DS(01) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 12-position connector operates at 2.5mm pitch and features shrouded 4-wall construction with push-pull fastening. The part is currently active in production with 792 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where form factor and performance requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-12P-2.5DS(01) is determined by the following critical parameters:

• Pitch - Mating: 0.098" (2.50mm) — must match exactly
• Number of Positions: 12 — must match exactly
• Number of Rows: 1 — must match exactly
• Connector Type: Header — must match exactly
• Contact Type: Male Pin — must match exactly
• Mounting Type: Through Hole, Right Angle — must match exactly
• Shrouding: Shrouded - 4 Wall — must match exactly
• Voltage Rating: 250V — must match or exceed
• Operating Temperature Range: -35°C ~ 85°C — substitute must cover or exceed this range
• Material Flammability Rating: UL94 V-0 — must match or exceed
• RoHS Status: RoHS Compliant — must maintain compliance

The Molex 0534261210 (Mini-Lock 53426 series) meets all critical electrical and mechanical parameters for direct substitution in applications requiring a 12-position, 2.5mm pitch right-angle header with shrouded construction.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0534261210 is qualified as a direct substitute for the DF1B-12P-2.5DS(01) based on the following criteria:

All critical electrical and mechanical parameters align between the two parts. Both connectors maintain UL94 V-0 flammability compliance and operate at 250V. The Molex substitute provides an extended operating temperature range (-40°C ~ 105°C) compared to the original specification (-35°C ~ 85°C), offering improved thermal performance margins.

Both parts maintain RoHS compliance status and identical moisture sensitivity levels. The substitute is available in higher inventory (32,293 units) compared to the original part (792 units), providing supply chain flexibility.

The primary differences are in contact material composition (Brass vs. Phosphor Bronze), contact finish (Gold vs. Tin), and fastening mechanism (Push-Pull vs. Locking Ramp). These differences do not affect electrical or mechanical interchangeability for standard board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0534261210 be used as a direct replacement for the DF1B-12P-2.5DS(01)?

A: Yes. Both connectors share identical pitch (2.5mm), position count (12), row configuration (1), mounting type (through-hole right-angle), and shrouding (4-wall). Electrical ratings and compliance certifications are equivalent.

Q: What are the differences between these two connectors?

A: The primary differences are contact material (Hirose uses Brass; Molex uses Phosphor Bronze), contact finish (Hirose uses Gold; Molex uses Tin), and fastening mechanism (Hirose uses Push-Pull; Molex uses Locking Ramp). These differences do not affect mating compatibility or electrical performance in standard applications.

Q: Does the Molex substitute offer any performance advantages?

A: The Molex 0534261210 provides an extended operating temperature range (-40°C ~ 105°C vs. -35°C ~ 85°C), offering improved thermal margin. Both parts maintain identical voltage ratings and flammability compliance.

Q: Are there packaging differences between these parts?

A: Yes. The Hirose DF1B-12P-2.5DS(01) is supplied in Bulk packaging, while the Molex 0534261210 is supplied in Tray packaging. This affects handling and storage but does not impact component functionality.

Q: Do both parts maintain RoHS compliance?

A: Yes. The Hirose part is RoHS Compliant, and the Molex part is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
