Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DCP37S565TLF is determined by strict alignment of the following core parameters:

Critical Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Contact material: Copper Alloy
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

All four substitute parts (09664127601, 09664526611, 09664526612, 09664527611) manufactured by HARTING meet these critical parameters. Variations in flange feature design (M3 or 4-40 threaded options), contact finish specification, and board lock features represent acceptable mechanical and functional differences that do not compromise electrical compatibility or core connector functionality.

Parameter Comparison

Engineering Selection Recommendations

All four HARTING substitute parts (09664127601, 09664526611, 09664526612, 09664527611) are active production components with ROHS3 compliance and REACH unaffected status, meeting or exceeding the regulatory requirements of the primary DCP37S565TLF part. Selection among substitutes should be based on mechanical integration requirements:

09664127601: Suitable for applications requiring M3 threaded flange mounting without board lock features. Represents the baseline HARTING equivalent.

09664526611 and 09664527611: Both include board lock features for enhanced mechanical retention. 09664526611 uses M3 threaded flange; 09664527611 also uses M3 threaded flange. These variants are appropriate for applications requiring positive mechanical locking during mating cycles.

09664526612: Features 4-40 threaded flange with board lock, providing alternative fastening compatibility for designs utilizing 4-40 threaded mounting holes.

Current inventory levels support immediate procurement across all substitute options. The 0.003" (0.10mm) difference in backset spacing and the 1.0A reduction in current rating per contact for HARTING parts are within acceptable tolerance for standard D-Sub 37-position applications.

Frequently Asked Questions (FAQ)

Q: Can HARTING parts 09664526611, 09664526612, and 09664527611 be used interchangeably with the DCP37S565TLF?

A: Yes, these parts are electrically and mechanically compatible substitutes. All maintain the same 37-position, 2-row configuration, shell size 4 (DC, C), through-hole right-angle solder termination, and operating temperature range. Selection depends on flange mounting requirements: M3 threaded (09664526611, 09664527611) or 4-40 threaded (09664526612). Board lock features on 09664526611, 09664526612, and 09664527611 provide additional mechanical retention not present on the DCP37S565TLF or 09664127601.

Q: What is the significance of the current rating difference (7.5A vs. 6.5A per contact)?

A: The DCP37S565TLF supports 7.5A per contact, while HARTING substitutes support 6.5A per contact. For applications operating at or below 6.5A per contact, this difference is not a limiting factor. Applications requiring the full 7.5A rating should retain the DCP37S565TLF or evaluate specific current requirements against actual circuit demands.

Q: Are there differences in contact finish between the main part and substitutes?

A: The DCP37S565TLF specifies gold-plated contacts with 30.0µin (0.76µm) thickness. HARTING substitute parts do not specify contact finish in the provided data. Both connector families use copper alloy contact material and are suitable for standard signal applications. Contact finish specifications should be confirmed with HARTING if gold plating is a critical design requirement.

Q: What is the difference between the flange options (M3, 4-40, Unthreaded)?

A: Flange features determine mounting method. The DCP37S565TLF uses an unthreaded housing/shell flange. HARTING substitutes offer M3 metric threaded (09664127601, 09664526611, 09664527611) or 4-40 UNC threaded (09664526612) flanges. Selection depends on PCB or chassis mounting hole specifications. Unthreaded flanges rely on friction fit or adhesive; threaded flanges provide screw-based mechanical retention.

Q: Do the board lock features affect electrical performance?

A: No. Board lock features (present on 09664526611, 09664526612, 09664527611) provide mechanical retention during mating and do not alter electrical characteristics. These features prevent accidental disconnection and are beneficial in vibration-prone or high-reliability applications.

Q: Are all parts RoHS compliant?

A: Yes. The DCP37S565TLF is RoHS Compliant. All HARTING substitutes are ROHS3 Compliant, which represents an updated compliance standard. Both statuses satisfy RoHS directive requirements.
