S15B-XH-A Equivalent & Substitute Parts

Part Overview

The S15B-XH-A is a rectangular connector header manufactured by JST Sales America Inc., designed for through-hole, right-angle board-to-cable/wire applications. This 15-position connector operates at 3A current rating and 250V voltage rating, with an operating temperature range of -25°C to 85°C. The part is currently in active production status with 1071 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design flexibility requires alternative connector solutions that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

The DF1BZ-15P-2.5DS qualifies as a substitute for the S15B-XH-A based on the following critical parameters:

• Number of Positions: Both parts feature 15 positions
• Pitch - Mating: Both maintain 0.098" (2.50mm) pitch spacing
• Connector Type: Both are header connectors
• Contact Type: Both use male pin contacts
• Mounting Type: Both are through-hole, right-angle configurations
• Shrouding: Both feature shrouded 4-wall design
• Contact Material: Both use brass contacts
• Insulation Material: Both use polyamide/nylon insulation
• Material Flammability Rating: Both meet UL94 V-0 standard
• RoHS Compliance: Both are RoHS compliant

Substitution is valid where these core parameters align. Differences in secondary specifications (voltage rating, current rating, operating temperature range, fastening type, and product status) must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-15P-2.5DS from Hirose Electric Co Ltd is electrically and mechanically compatible with the S15B-XH-A for applications requiring 15-position, 2.5mm pitch header connectors in through-hole, right-angle configurations.

Compatibility Considerations:

The S15B-XH-A operates at 250V and 3A ratings, while the DF1BZ-15P-2.5DS is rated at 150V with unspecified current rating. Applications operating above 150V or requiring the full 3A current specification must verify that the substitute part meets electrical requirements.

The DF1BZ-15P-2.5DS features a wider operating temperature range (-35°C to 85°C versus -25°C to 85°C), providing additional thermal margin in low-temperature environments.

Mechanical differences include fastening type (Detent Lock versus Push-Pull) and minor variations in contact post length (0.134" versus 0.142") and insulation height (0.240" versus 0.224"). These differences require PCB layout verification to ensure proper mating and mechanical clearance.

The S15B-XH-A maintains active production status with established supply availability. The DF1BZ-15P-2.5DS carries Last Time Buy status, indicating limited future availability.

Frequently Asked Questions (FAQ)

Q: Can the DF1BZ-15P-2.5DS directly replace the S15B-XH-A in existing designs?

A: Direct replacement is possible only when application voltage requirements do not exceed 150V and current requirements are within the DF1BZ-15P-2.5DS specification. The 2.5mm pitch and 15-position configuration are identical. PCB layout must accommodate the minor differences in contact post length and insulation height.

Q: What are the key differences between these two connector headers?

A: The primary differences are voltage rating (250V versus 150V), fastening mechanism (Detent Lock versus Push-Pull), contact post length (0.134" versus 0.142"), and insulation height (0.240" versus 0.224"). Both maintain identical pitch spacing, position count, and shrouding configuration.

Q: Are both parts RoHS compliant?

A: Yes. The S15B-XH-A is ROHS3 compliant, and the DF1BZ-15P-2.5DS is RoHS compliant. Both meet flammability requirements at UL94 V-0.

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

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for new designs?

A: The S15B-XH-A is recommended for new designs due to active production status and higher voltage/current ratings. The DF1BZ-15P-2.5DS should be considered only when supply constraints require substitution and application parameters fall within its electrical specifications.

Q: Are the mating contacts compatible between these two connector series?

A: Both connectors use 0.098" (2.50mm) pitch male pin contacts with tin finish on brass material. Mating compatibility depends on the receptacle connector used in the application. Verify receptacle specifications against both header series.
