Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of core electrical and mechanical parameters. The following parameters establish substitution validity:

Critical Matching Parameters:

• Connector Type (Header configuration)
• Contact Type (Male Pin)
• Number of Positions (4)
• Number of Rows (2)
• Pitch - Mating (0.100" / 2.54mm)
• Row Spacing - Mating (0.100" / 2.54mm)
• Mounting Type (Through Hole, Right Angle)
• Termination (Solder)
• Fastening Type (Push-Pull)
• Contact Shape (Square)
• Style (Board to Board or Cable)
• Shrouding (Unshrouded)

Variable Parameters Permitting Substitution:

• Contact Material (Brass vs. Phosphor Bronze)
• Contact Finish - Mating (Gold specifications)
• Contact Finish - Post (Tin vs. Gold)
• Insulation Material (PBT vs. Liquid Crystal Polymer)
• Insulation Color
• Contact Length - Mating (within mechanical compatibility range)
• Contact Length - Post (within mechanical compatibility range)
• Insulation Height (within mechanical compatibility range)
• Operating Temperature Range (extended ranges acceptable)
• RoHS Compliance Status (RoHS Compliant and ROHS3 Compliant both acceptable)

All three substitute parts satisfy the critical matching parameters and are therefore valid equivalents for the TE Connectivity 826634-2.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and comply with applicable regulatory standards. Selection between the TE Connectivity 826634-2 and substitute parts should be based on the following engineering considerations:

TE Connectivity 826634-2 (Primary Part):

• Brass contact material with tin-plated posts
• Operating temperature range: -65°C ~ 105°C
• RoHS Compliant certification
• Green insulation color for visual identification
• 5A current rating specification

Samtec HTSW-102-09-G-D-RA:

• Phosphor bronze contact material with gold-plated posts
• Extended operating temperature range: -55°C ~ 125°C
• ROHS3 Compliant certification
• Liquid Crystal Polymer insulation material
• Longer contact post length (0.290" vs. 0.126")

Samtec TSW-102-08-F-D-RA:

• Phosphor bronze contact material with tin-plated posts
• Extended operating temperature range: -55°C ~ 125°C
• ROHS3 Compliant certification
• Shortest contact post length (0.090")
• Highest inventory availability (1072 Pcs)

Samtec TSW-102-22-G-D-RA:

• Phosphor bronze contact material with gold-plated posts
• Extended operating temperature range: -55°C ~ 125°C
• ROHS3 Compliant certification
• Moderate contact post length (0.190")
• Highest inventory availability (6364 Pcs)

All substitute parts are certified to UL94 V-0 flammability standards and maintain compatibility with the critical mating parameters of the primary part.

Frequently Asked Questions (FAQ)

Q: Can Samtec TSW-102-22-G-D-RA be used as a direct replacement for TE Connectivity 826634-2?

A: Yes. Both parts share identical critical parameters: 4-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination, and push-pull fastening. The TSW-102-22-G-D-RA features phosphor bronze contacts with gold plating on both mating and post surfaces, compared to the brass contacts with tin-plated posts of the 826634-2. Both maintain UL94 V-0 flammability compliance and are suitable for board-to-board or cable applications.

Q: What is the difference between contact post lengths across the substitute options?

A: Contact post length varies among substitutes: TE Connectivity 826634-2 has 0.126" (3.20mm), Samtec TSW-102-08-F-D-RA has 0.090" (2.29mm), Samtec TSW-102-22-G-D-RA has 0.190" (4.83mm), and Samtec HTSW-102-09-G-D-RA has 0.290" (7.37mm). Post length affects solder joint depth and PCB penetration. Selection depends on specific PCB thickness and solder joint requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part TE Connectivity 826634-2 is RoHS Compliant. All three substitute parts are ROHS3 Compliant, which represents an updated compliance standard. Both certifications satisfy RoHS requirements for lead-free and restricted substance compliance.

Q: What is the operating temperature difference between the primary part and substitutes?

A: The TE Connectivity 826634-2 operates from -65°C to 105°C. All three Samtec substitutes operate from -55°C to 125°C, providing an extended upper temperature limit of 20°C higher. The lower temperature limit is 10°C higher on substitutes. Applications requiring operation below -55°C must use the primary TE Connectivity part.

Q: How do contact materials differ between options?

A: The TE Connectivity 826634-2 uses brass contacts with gold-plated mating surfaces and tin-plated posts. All Samtec substitutes use phosphor bronze contacts. Phosphor bronze offers enhanced spring properties and durability compared to brass. Contact finish specifications vary: TSW-102-08-F-D-RA maintains tin plating on posts, while TSW-102-22-G-D-RA and HTSW-102-09-G-D-RA feature gold plating on both mating and post surfaces.

Q: What insulation material differences exist?

A: The TE Connectivity 826634-2 and Samtec TSW series use Polybutylene Terephthalate (PBT) insulation. The Samtec HTSW-102-09-G-D-RA uses Liquid Crystal Polymer (LCP) insulation, which offers superior dimensional stability and lower moisture absorption. Both materials maintain UL94 V-0 flammability ratings.

Q: Which substitute part has the highest inventory availability?

A: Samtec TSW-102-22-G-D-RA has the highest inventory availability at 6364 pieces, followed by TSW-102-08-F-D-RA at 1072 pieces and HTSW-102-09-G-D-RA at 720 pieces. The primary TE Connectivity 826634-2 has 721 pieces in stock.

Q: Are all parts suitable for board-to-board and cable applications?

A: Yes. All parts are classified as "Board to Board or Cable" style connectors. The right-angle mounting configuration and push-pull fastening mechanism support both application types.

Q: What is the significance of MSL (Moisture Sensitivity Level) ratings?

A: The TE Connectivity 826634-2 and Samtec TSW series are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling. The Samtec HTSW-102-09-G-D-RA is rated "Not Applicable," indicating the LCP insulation material does not require moisture sensitivity classification. Both ratings are acceptable for standard manufacturing environments.
