Substitute Part Grouping Explanation

Substitute parts for the WR-DSUB 61800929321 are identified based on the following critical parameters that determine functional equivalence:

Matching Criteria:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Shell size and layout: 1 (DE, E)
• Mounting type: Through Hole
• Termination method: Solder
• Current rating: 3A minimum
• Voltage rating: Equal to or greater than 125V
• Operating temperature range: Must encompass -40°C to 85°C
• Shell material finish: Steel, Tin Plated
• Contact finish: Gold
• RoHS compliance: ROHS3 Compliant
• Product status: Active

The Adam Tech DE09-ST-1-BL-JS qualifies as a substitute part because it satisfies all critical electrical and mechanical parameters. While minor differences exist in contact material (Brass vs. Copper Alloy), dielectric composition (Glass Filled PBT vs. standard PBT), and operating temperature upper range (85°C vs. 85°C), these variations do not prevent functional substitution in applications designed for the WR-DSUB 61800929321.

Parameter Comparison

Engineering Selection Recommendations

Both the WR-DSUB 61800929321 and DE09-ST-1-BL-JS are active products with ROHS3 compliance, ensuring regulatory alignment for current manufacturing standards. The DE09-ST-1-BL-JS provides enhanced voltage rating (250VAC vs. 125V) and extended lower operating temperature capability (-55°C vs. -40°C), making it suitable for applications requiring greater thermal or electrical margin. The Adam Tech substitute maintains identical current rating, connector geometry, and solder termination compatibility, enabling direct PCB layout reuse without redesign. Selection between these parts should be based on specific application voltage and temperature requirements, with the Adam Tech option providing additional operational headroom in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the DE09-ST-1-BL-JS directly replace the WR-DSUB 61800929321 on existing PCBs?

A: Yes. Both connectors share identical shell size (DE/E), 9-position configuration, through-hole mounting footprint, and solder termination. PCB layouts designed for the WR-DSUB 61800929321 accommodate the DE09-ST-1-BL-JS without modification.

Q: What is the difference in contact material between these parts?

A: The WR-DSUB 61800929321 uses Copper Alloy contacts, while the DE09-ST-1-BL-JS uses Brass contacts. Both materials are gold-plated and suitable for signal transmission in D-Sub applications. Contact material differences do not affect electrical performance in standard signal applications.

Q: Why does the DE09-ST-1-BL-JS have a higher voltage rating?

A: The Adam Tech part is rated for 250VAC compared to the Würth Elektronik 125V rating. This reflects design margin differences between manufacturers. For applications operating at 125V or below, both parts are functionally equivalent.

Q: Are there packaging differences between these connectors?

A: Both parts are supplied in trays. The WR-DSUB 61800929321 has 931 pieces in stock, while the DE09-ST-1-BL-JS has 1071 pieces available. Packaging format is identical.

Q: What is the significance of the glass-filled dielectric in the DE09-ST-1-BL-JS?

A: Glass-filled PBT provides enhanced mechanical strength and thermal stability compared to standard PBT. This does not affect electrical substitution compatibility but may provide improved durability in high-vibration or thermal cycling environments.

Q: Do both connectors support the same flange mounting options?

A: The WR-DSUB 61800929321 features mating-side female screwlock (4-40). The DE09-ST-1-BL-JS includes both board-side and mating-side (4-40) options, providing additional mounting flexibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the WR-DSUB 61800929321 and DE09-ST-1-BL-JS are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.
