Key Parameters

Substitute Part Grouping Explanation

Substitution of the RRD1010K is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit configuration (BCD)
• Number of positions (10)
• Current rating (0.4VA)
• Voltage rating (20VAC/DC)

Mechanical Compatibility:

• Actuator type (Rotary for Tool)
• Actuator level (Flush, Recessed)
• Mounting type (Through Hole)
• Pitch spacing (0.100" / 2.54mm)
• Height above board (0.287" / 7.30mm)
• Contact material and finish (Copper Alloy, Gold)

Environmental Specifications:

• Operating temperature range (-30°C ~ 85°C)
• Mechanical and electrical life (10,000 Steps)

The substitute part 1825444-1 meets all these criteria and is classified as an active product, providing a direct functional replacement for the obsolete RRD1010K.

Parameter Comparison

Engineering Selection Recommendations

The RRD1010K is classified as obsolete and no longer in active production. The substitute part 1825444-1 is an active product from the same manufacturer and series, providing full electrical and mechanical compatibility.

Selection Basis:

1. Product Status: The RRD1010K obsolescence necessitates transition to an active equivalent. Part 1825444-1 maintains active product status, ensuring long-term availability and supply chain continuity.

2. Functional Equivalence: All critical electrical parameters (BCD circuit, 10 positions, 0.4VA, 20VAC/DC) and mechanical specifications (through-hole mounting, 0.100" pitch, flush recessed actuator, 0.287" height) are identical between the main part and substitute.

3. Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, ensuring regulatory consistency. The RRD1010K is RoHS non-compliant; the substitute part 1825444-1 has RoHS status listed as not applicable, reflecting its active product classification.

4. Environmental Specifications: Operating temperature range (-30°C ~ 85°C), mechanical life (10,000 steps), and electrical life (10,000 steps) are fully matched.

5. Packaging Consideration: The substitute part 1825444-1 is supplied in bulk packaging, whereas the main part packaging is unspecified. Procurement should confirm packaging requirements for assembly operations.

Frequently Asked Questions (FAQ)

Q: Can 1825444-1 be used as a direct replacement for RRD1010K in existing designs?

A: Yes. The 1825444-1 is electrically and mechanically equivalent to the RRD1010K across all specified parameters, including circuit type, position count, voltage/current ratings, actuator configuration, mounting type, and pitch spacing. No design modifications are required.

Q: What is the primary reason for substitution?

A: The RRD1010K is classified as obsolete and no longer manufactured. The 1825444-1 is an active product from TE Connectivity ALCOSWITCH Switches that provides identical functionality and specifications.

Q: Are there differences in contact finish between the two parts?

A: The RRD1010K specifies gold contact finish, while the 1825444-1 specifies gold alloy contact finish. Both are gold-based finishes on copper alloy substrates and are functionally equivalent for the specified electrical parameters (0.4VA, 20VAC/DC).

Q: What is the difference in packaging between these parts?

A: The RRD1010K packaging is unspecified in available documentation. The 1825444-1 is supplied in bulk packaging. Procurement specifications should confirm packaging requirements for assembly and handling.

Q: Are the regulatory classifications identical?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. RoHS compliance status differs: RRD1010K is RoHS non-compliant; 1825444-1 is listed as not applicable, reflecting its active product status.

Q: What is the mechanical life specification for both parts?

A: Both the RRD1010K and 1825444-1 are rated for 10,000 mechanical steps and 10,000 electrical steps, providing identical operational durability.

Q: Can these parts be used in washable applications?

A: Yes. Both the RRD1010K and 1825444-1 are specified as washable, supporting cleaning processes in manufacturing environments.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: 0.287" (7.30mm) height above board, 0.394" (10.01mm) length, and 0.100" (2.54mm) pitch spacing. PCB layout and mounting hole patterns are compatible.
